[sane-devel] I have the Epson Perfection 2480 and 2580 for testing

It seems the 2580 behaves somewhat different, although it uses the 
same USB ID. Up to now I have no idea what's going wrong.

The log you sent for the 2580 indicates an error in 
snapscani_usb_open() which is only a small wrapper for 
sanei_usb_open(). Can you provide logs with SANE_DEBUG_SANEI_USB=255 
as well?

The delays are annoying, but it seems that all delays are requested by 
the scanner. You can try to reduce the number of retries for the 
test_unit_ready in snapscan-scsi.c, line 1008 and see if that works 
any better.

There's nothing obvious in the log. Can you run xsane in gdb and 
create a stacktrace (command "bt" IIRC) after the crash?
